Cartridge Loading for a phono pre amp

@noromance : " While mechanical impact does occur as a result of electrical load- there is some back emf necessarily generated by the signal current that affects the mechanical motion, but a quick back of the envelope calculation using Lenz’s law and the 10uH cartridge suggests a 2 orders of magnitude difference between the generated signal and the back EMF for a 100 ohm load at 20kHz- certainly not enough to cause tracking issue. "

Can you show the envelope and the equations?

JC: " Tonearm cable inductance is typically dwarfed by the inductance of the cartridge signal coils (Lyra PhonoPipe cable inductance 0.75uH, Lyra Kleos coil inductance 9uH), so it makes no sense to reduce the cable inductance if the price to be paid is greater capacitance (which is usually what happens).

When authoring the documentation for our post-2009 cartridges, I went up as high as 600pF cable capacitance (to cover audiophiles who may keep their turntable in a separate room / closet). The official loading recommendations for the Delos, Kleos, Atlas, and Etna reflect this wide range of cable capacitances, and the inclusion of highly capacitive cables for special circumstances is why you may see loading values as low as 95 ohms suggested in our literature.

I asked about compliance as a function of loading.
You provided frequency response as a function of loading.

It is like wanting an omelet, and receiving a half boiled egg, and claiming that the/a meal has been prepared.

We should probably just let it go.
